When I’m making music or mixing, I like to run my tracks through a group bus called that I call “Pre-Stereo Out”. This allows me to process everything on that group channel as if it were the master bus without affecting tracks that I have loaded in for references.
Currently, when you add a track, you can select an audio output, and that audio output will show up as the default output for the next track you add too. But if you close the project and open it again, that default output gets reset. This is a problem for me often (mostly when making music rather than mixing) because I end up forgetting to set the audio output to the Pre Stereo Out channel and then I have to meticulously go through my project and manually re-route everything.
So if Cubase could just remember those default audio outputs on a project by project basis, that would be so awesome!
